To all whom 711'; may con/cent:

Waukee, in the county of lviilwaulree and tilts-to of Wisconsin, have invented certain new and useful lmpr venientsiu Heating- Systems, of which the following is a specification.

My invention relates to that class of heating systems in which an exhausting apparatus is placed in communication with the radiator or radiators to remove the air or produce a partial vacuum therein, and thereby to i'acilitate the distribution of the heating agent'or Such systems being already Well known to the public need not he particularly described herein The invention consists in providing the ri-idiutors each with asupply or controlling valve and with a fluid-pressure motor for tuating said valve, connecting the ilui l--pres'- sure motor with the exhaust pipe or system, providingsaid exhaust-pipe with. a vent at point hetween the 'iauster and the fluidu'essure motor, and "pplyingg; to said vent thermostatic valve v-xl'icrehy the one exhaust system is caused to exhaust the air from the radiators and to control and actuate the supply or controlling valves.

"ihe iiuid-rnoter valve and the thermcstati vent-controller ermaloycd are not specifically claimed, heing those oi the well-known Easton type; hut the combination whereby one exhaust system is made to serve both purposes and to insure'the proper relative Working of the different parts of the/system new and affords an exceedingly simple, cheap, and eliicicnt meansoi temperature regulation and control. v

The accompanying drawing represents the improved apparatus in elevation with portions in section. then hole being, of a diagrammatic nature.

A indicates a radiator; ll, its supply-pipe provided with a main oontrolling-valve C; D, the return or discharge pipe; l an valve or vent for the radiator; F, an "Xhaus't-pipe eoininunical hy a hrs-rich c with air valve or vent l and (l exhaustins, apparatus, herein rcpres-uuitcd as a positively acting pinup.

As shown main valve (1 is carried by a steml), connected with the flexible dizuwhragm 0 of a fluid-pressure motor ll, said stem being encircled by a spring d, which tenc s always to open valve C.

When pipe li is sealed against the atmos phere, the suction of pump or exhauster G produces a partial vacuum in the fluid-chamber of motor H, and as a consequence the pressure of the atmosphere upon its diaphragm causes the latter to collapse into the chamber of the motor and in so doing to lift and close valve (3, thereby shutting oil the supply of heating medium or agent. Ii, however, the

eipe F he freely vented or opened to the outer atmosphere, the suction or exhaust from motor ill will he insnilicient to close valve (J, and conser uently the radiator Will'he supplied with the heating agent or medium, this being the relation of parts represented in the drawing.

Pipe F is represented as turnishedwith a vent-pipe a, to the vent-orifice of which is applied a thermostatic valve I. When the main valve U is arranged to opcn against and to '75,

close with the suction, as here represented, valve 1 will be arranged toelose upon a rise eit' temperature; hut if the main valve he arranged to open with or by the suction and to close when suction ceases valve l Will of course he arranged to close upon a fall of te1nperature. Being set to close as the temperature rises to a predetermined limit, under the em hodiinent oi" the invention here representml valve 1 will seal the pipe l against communi- 8 5 cation with the atmosphere Whenever the apartment is sufiiciently' warmed, and the consequent suction upon the diaphragm c of mo- ,tor H will close valve C and shut oil the heat JUE tor of condensation or passage of steam, but 0 prevent ingress of air, which would interfere with the proper exhausting action.

' pacity than pipe F or vent 13, so that it shall of capacity. The second provisionis, how ever, important, as otherwise the exhausting apparatus might maintain a constant suction or exhausting action in the fluid-pressure motor, and thereby cause the main veive to re main always closed. .While it is possible to so nicely adjust the capacity of the exhausting" apparatus to the size of the vent and the capacity of theexhuust-pipe as to operate Without the restriction, it is not considered wise to adopt such construction.
